Overview

Note:

When passing ModifyReplicationGroupShardConfigurationMessage as input to an Aws::Client method, you can use a vanilla Hash:

{
  replication_group_id: "String", # required
  node_group_count: 1, # required
  apply_immediately: false, # required
  resharding_configuration: [
    {
      preferred_availability_zones: ["String"],
    },
  ],
  node_groups_to_remove: ["String"],
}

Represents the input for a ModifyReplicationGroupShardConfiguration operation.

Instance Attribute Details

#apply_immediatelyBoolean

Indicates that the shard reconfiguration process begins immediately. At present, the only permitted value for this parameter is true.

Value: true

Returns:

  • (Boolean)

    Indicates that the shard reconfiguration process begins immediately.

#node_group_countInteger

The number of node groups (shards) that results from the modification of the shard configuration.

Returns:

  • (Integer)

    The number of node groups (shards) that results from the modification of the shard configuration.

#node_groups_to_removeArray<String>

If the value of NodeGroupCount is less than the current number of node groups (shards), NodeGroupsToRemove is a required list of node group ids to remove from the cluster.

Returns:

  • (Array<String>)

    If the value of NodeGroupCount is less than the current number of node groups (shards), NodeGroupsToRemove is a required list of node group ids to remove from the cluster.

#replication_group_idString

The name of the Redis (cluster mode enabled) cluster (replication group) on which the shards are to be configured.

Returns:

  • (String)

    The name of the Redis (cluster mode enabled) cluster (replication group) on which the shards are to be configured.

#resharding_configurationArray<Types::ReshardingConfiguration>

Specifies the preferred availability zones for each node group in the cluster. If the value of NodeGroupCount is greater than the current number of node groups (shards), you can use this parameter to specify the preferred availability zones of the cluster\'s shards. If you omit this parameter ElastiCache selects availability zones for you.

You can specify this parameter only if the value of NodeGroupCount is greater than the current number of node groups (shards).

Returns:
